Non-contact voltageWith the red NCV tab on the tip of the meter closeto an AC voltage, press and hold the NCV button.The NCV LED will light and the beeper will beep. Thecloser you get to AC voltage, the louder the beep.The NCV function is sensitive enough to detect24VAC on thermostats.Hi voltage indicatorIn any VAC/VDC range, when you touch a voltagegreater than 30V, the beeper will beep and the red Hi-V LED will blink. BE CAREFUL!MicroampsFor measuring the flame diode current in a heatercontrol.CapacitanceFor motor-start and motor-run capacitors.Disconnect the capacitor from power first. Short theterminals to discharge the capacitors. Disconnectany resistors that might be between the terminals ofthe capacitor.MIN/MAXPress MIN/MAX once to begin recording MIN andMAX. Press MIN/MAX to select current reading’s MINor MAX. Hold down for 2 seconds to exit MIN/MAXfunction.TemperaturePlug any K-type thermocouple directly into themeter to measure temperature. Temperature meas-urement will be accurate even in fast changing envi-ronments because of excellent temperature compen-sation. One thermocouple is included. No adapter isrequired.Backlight (HS36)Press the button to activate the backlight forapproximately 60 seconds.True RMS (HS36)Digital multimeters use two different types of ACsensing. The most common is average sensing, nor-malized to a true RMS value of a sine wave. Theother is true RMS sensing. The actual true RMSvalue is sensed for a wave form within the limits ofthe crest factor. Either sensing method will give thesame results on a clean sine wave but they may dif-fer on a non-sinusoidal waveform.Field °F calibrationFor accuracies of ±1°F, calibrate to a known tem-perature. A glass of stabilized ice water is very closeto 32°F (0°C) and is usually very convenient but anyknown temperature can be used.1. Select the 400°F range.2. Remove back case and hold the battery in placewith a rubber band so terminals are touching.3. Stabilize a large cup of ice water.4. Immerse the thermocouple probe and let it stabi-lize.5. Adjust VR3 (lower right corner of PCB) to getclose to 32°F (0°C) then adjust VR2 (left of VR3)to get within 0.1°F (0.05°C) of 32°F (0°C).6. To calibrate in °C, close the jumper that is to theleft of VR3.Disable auto offSet to OFF position, press and hold RNG (HS35)or MIN/MAX (HS36) button while turning rotary dialto desired range position. Release the button whenLCD displays normally. Note: “APO” annunciator willbe missing from the display. The Auto Power Offmode is on when “APO” indicated on the display.Attach to Fieldpiece accessory headConnect your Fieldpiece accessory head directlyto the top of HS series and switch to range indicatedby head.Symbols used:Caution, risk of electric shockCaution, refer to manual.GroundDouble insulationUsing & storing test leadsBecause the wire insulation is silicone the leadswill stay flexible in cold weather and will not melt ifbumped by a soldering iron.Disconnect top half of test lead and plug tip direct-ly into meter to make voltage testing easy. Use withincluded alligator clip (ASA2) as shown for even eas-ier operation.For convenient lead storage, wrap the leads asshown. Pull leads around front between overhangingtips, twist, and pull over one of the lead plugs.OPERATOR’S MANUALFor your safety...General: Disconnect the test leads before openingthe case. Inspect the test leads for damage to theinsulation or exposed metal. Replace if suspect.Never ground yourself when taking electrical meas-urements. Do not touch exposed metal pipes, outlets,fixtures, etc., which might be at ground potential.Keep your body isolated from ground by using dryclothing, rubber shoes, rubber mats, or any approvedinsulating material. When disconnecting from a cir-cuit, disconnect the "RED" lead first, then the com-mon lead. Work with others. Use one hand for test-ing. Turn off power to the circuit under test before cut-ting, unsoldering, or breaking the circuit. Keep yourfingers behind the finger guards on the probes. Donot measure resistance when circuit is powered. Donot apply more than rated voltage between input andground.All voltage tests: All voltage ranges will withstandup to 600V. Do not apply more than 600VDC or600VAC.AC tests: Disconnect the meter from the circuitbefore turning any inductor off, including motors,transformers, and solenoids. High voltage transientscan damage the meter beyond repair. Do not useduring electrical storms.MaintenanceClean the exterior with clean dry cloth. Do not useliquid.Battery replacement: When the multimeter dis-plays " " the battery must be replaced. Disconnectand unplug leads, turn meter off, and remove the bat-tery cover. Replace the battery with a NEDA type1604 9V battery.Limited warrantyThis meter is warranted against defects in materi-al or workmanship for one year from date of pur-chase. Fieldpiece will replace or repair the defectiveunit, at its option, subject to verification of the defect.This warranty does not apply to defects resultingfrom abuse, neglect, accident, unauthorized repair,alteration, or unreasonable use of the instrument.Any implied warranties arising from the sale of aFieldpiece product, including but not limited toimplied warranties of merchantability and fitness for aparticular purpose, are limited to the above.Fieldpiece shall not be liable for loss of use of theinstrument or other incidental or consequential dam-ages, expenses, or economic loss, or for any claim ofsuch damage, expenses, or economic loss.State laws vary. The above limitations or exclu-sions may not apply to you.ServiceReturn any defective HS35/36 to Fieldpiece forwarranty service along with proof of purchase.Contact Fieldpiece for out of warranty repair charges.!AUTO-RANGINGDIGITAL STICKMETERS:HS35HS36Function LegendContinuityVDC Volts DCMFD Capacitance°C/°F TemperatureμADC Microamps DCΩ ResistanceHz FrequencyVAC Volts ACv08actoolsupply.comactoolsupply.comactoolsupply.comFieldpiece HS36 True RMS Digital Multimeter |
